IPC: G03G15/00
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate the waste of a copying paper and to shorten copying time by inhibiting a copying action for the rear of the last document which is blank in both-side document/one-side copying mode when information that the rear of the last document is in a blank state is inputted. CONSTITUTION:The both-side document/one-side copying mode is set and the information that the rear of the last document is in the blank state is inputted, then a copying key is depressed. Thus, the documents where images exist on both sides placed on a document platen 41 are automatically set one by one on a contact glass 2, a belt-like photosensitive body 5 is exposed to reflected light from the document, and development is performed, then an obtained toner image is transferred on a paper by a transfer charge 9. After performing copying processing for the set number of papers, the document is inverted and the copying processing of the image on the rear is performed. The processing is repeated, and the copying processing completed based on the above information without performing the copying processing of the rear of the last document.

Abstract: PURPOSE:To reduce the size of a device and prevent copy paper from wrinkling by providing a couple of pressure rollers which wind an endless belt around a fixing roller and press the belt, and applying more press-contacting force from the downstream-side roller than from the upstream-side roller. CONSTITUTION:The endless belt 15 is extended between a press-contacting roller 11 fitted to a substrate 12 and an auxiliary roller 13. The substrate 12 is energized counterclockwise around a shaft 16 with a spring 17 to press the press- contacting roller 11 and auxiliary roller 13 against the fixing roller 9, thereby winding the belt 15 around the fixing roller 9 by a center angle L. The auxiliary roller 13 is energized with a spring 18 toward the fixing roller 9 and the press- contacting force of the pressure-contacting roller 11 is set larger. Copy paper 20 is conveyed as shown by an arrow C to fix a toner image 19 between the belt 15 and fixing roller 9 with the heat of a heater 10 and the pressure of the belt 15, and then discharged from the device. Consequently, the device is reduced in size and photosensitive paper is prevented from wrinkling to take an excellent copy.

Filed: 1986-01-17
Abstract: PURPOSE:To process decoding of a sequence ladder quickly by reading data of relay addresses successively in the row sequence in each column with an instruction LOAD by a CPU and outputting AND after storing results of individual columns in N-number of temporary holding means. CONSTITUTION:Data to be subjected to NOT operation is preliminarily stored in a prescribed address. The CPU omitted in the figure outputs the inverse of a signal RD and address signals A15-A0 to read out contents of the address from a RAM 6 onto data busses and sets the signal on a data bus D7 to a flip-flop 1 through an EXOR gate 7. Since the inverse of the signal RD and the address signal A15 are outputted together, a counter 5 counts '1' through an AND gate 8. Results of individual columns are stored in flip-flops 1-4 in this manner, and flip-flops 1-4 function as shift registers, and a gate 11 is opened to output momently AND of results of individual columns obtained in an AND gate 12 to the data bus D7, and this AND is stored in an accumulator of the CPU. Thus, the processing is performed quickly with even a general CPU in case of decoding of the sequence ladder.

Abstract: PROBLEM TO BE SOLVED: To enable etching of a first conductive film and a second conductive film in the same etching process, by carrying out reactive ion-etching using a gas obtained by adding a predetermined quantity of gas containing at least one kind of atom of carbon, fluorine and nitrogen to a mixed gas of chlorine gas and oxygen gas. SOLUTION: By reactive ion etching (hereinafter referred to as RIE) using a gas obtained by adding a predetermined quantity of gas containing at least one kind of atom of C, N and F to a mixed gas of Cl2 and O2 , a W film 4 and TiN film 3 can be simultaneously etched at substantially the same etch rate. Because of anisotropic etching by RIE, expansion of a seam after work is extremely small. Therefore, by setting the rate of fluorine at approximately 0.05, the etch rate of the W film and that of the TiN film can be made substantially the same and the W film and the TiN film can be etched in the same etching process.

Title: Device for comparative inspection of photomask

IPC: G03F1/84
Filed: 1987-01-19
Abstract: PURPOSE:To perform a simultaneous comparative inspection or a simultaneous inspection of three or more photomasks, by taking a logical sum of the first and second optical groups and at least three pattern images and by providing a condensing apparatus by which images are formed by using coloration based on the logical sum. CONSTITUTION:Coloring light sources, for example, are composed of red light sources 1 and 2 as well as a green light source 3 and coloring light beams from respective coloring light sources 1-3 are separately irradiated from below to photomasks 4-6 in different processes. Then respective coloring light beams which penetrate through pattern parts of the photomasks 4-6 at every different process are condensed by taking the logical sum of the patterns with a condensing apparatus 7 and they are projected on condensed images 9 through a lens 8 where changes of magnification can be done easily. For instance, when a pattern E like a photomask 26 is incorrect, coloring light of a part K in the case where there is an incorrect pattern E is, for example, red at the condensed images 30, while coloring light of the part K in the case where there is no incorrect pattern E is, for example, orange. The checking of these coloring light beams enables operators to judge whether there is an incorrect photomask pattern or not.

Abstract: PURPOSE:To suppress the irregular energization of a transformer by providing a pair of switching elements and providing different control signals applied to the respective elements by a predetermined value. CONSTITUTION:A pair of switching transistors Q1, Q2 and a control circuit for controlling the transistors as designated by Xc is provided.
